AET: Implementing Anonymity Enhancing Techniques for MANETs Using Statistical Traffic Analysis

Abstract

Anonymous communication is the main issue in case of MANETs. It is difficult to find the source and destination of the communication link and the other nodes involved in it. Many anonymity enhancing techniques have been proposed based on packet encryption to protect the communication anonymity of mobile ad hoc networks (MANETs). However, MANETs are vulnerable under certain circumstances like passive attacks and traffic analysis attacks. Here we describe the traffic analysis problem, expose some of the methods and attacks that could infer MANETs are still weak under the passive attacks. To show how to discover the communication patterns without decrypting the captured packets, we present the paper AET using statistical traffic analysis.
